J105 In accordance with the present invention .the Inthe embodimentshown in Figures 4 and 5 lens frames l0 `are `connected. by an` adjustable the ,hook 16 is formed from a blank of resilient incise-bridge comprising a flexible.` apertured, material so thatwhen screw cap 12 is removed ymem'ber, such as a metallic chain 15, which cothe horn 22 of the hook may be grasped and drawnY foperates` with hook members, designated as a ioutwardly, as shown in Fig. 5, to position the end T 110 of the hook to facilitate attachment or detachment of the nose-bridge chain 15. When the length of the flexible nose bridge 15 has been desirably adjusted by slipping one or another link near the end of the chain over the end 23 of hook 16 the horn 22 is bent back against frame 10, as in Fig. 4, base 17 being cut away or slotted at 27 to accommodate thevupwardly extending portion of horn 22.

As in the arrangement previously described, the horn 22 oi hook 16 is conned within the threaded flange 24 of cap 12 so that the link of the chain cannot be drawn over the end 23 of the hook when the cap is replaced.

The end 23 of horn 22 projects inwardly above a ledge 28 formed by cutting away a part of the threaded rim adjacent recess 18 and resiliently engages the inner side of lens 14 adjacent the flange 13 of cap 12 when the latter is replaced. Thus, the end 23 of horn 22 acts to maintain lens 14 against flange 13 of cap 12 and is in turn acted on by the lens to press the portion 21 of hook .toward theunderlying portion 20 restricting the space therebetween and closing the bight 25 of hook 16 so that a linky of chain 15 is retained in the bight.

In the form shown in Figure 7 the horn 22 of the bridge retaining hook extends reversely to part 20 thereof and substantially parallel to the lens frame so that the end 23 of the horn is directed downwardly, rather than upwardly as in Figs. 2 5. Upon removal of lens cap 12 the effective length of the nose bridge may be adjusted by slipping the links over the end 23 of the horn. 'I'he hook is preferably of resilient material and when the lens cap is replaced the horn 22 bears against the exterior surface of the flange 24 of the cap and thus effectively retains the nose bridge in engagement with the hook.

Because of the natural tendency of the links of a chain to depend vertically when the chain is grasped to apply a link to hook 16, the application of a link to a hook may be more readily effected by holding the chain vertically and drawing the desired link over the end of the hook from the side. If desired, the end 23 of the hook 16 may -be formed with a lateral projection 30, as shown in Fig. 3, to facilitate slipping the chain links over the end of the hook.

It will be readily seen from the above description that the flexibly connected lens frames may be readily varied in their spacing to suit any particular wearer by merely adjusting the length of the flexible nose bridge which is securely held in its adjusted position against accidental detachment as described above. Various types of flexible nose bridges may be employed and other changes and variations may be made without departing from the invention and I desire to include all such changes and variations within the scope of the appended claims.

What I claim is:

1. In a pair of goggles having lens frames, lens retaining caps thereon and a linked nose-bridge for connecting said frames; bridge retaining members xed to said frames and having extending loop portions adapted to seat determined links of said nose bridge and inwardly extending ends lockingly engaged within said caps.

2. In a pair of goggles having lens frames and a flexible, apertured, nose-bridge for connecting said frames; hooks mounted on said frames and having horns extending adjacent the sides of said frames for selectively engaging apertures of said nose-bridge to eilect a desired spacing of said frames; and lens retaining caps on said frames enclosing the ends of the horns of said hooks for retaining said nose-bridge in engagement with said hooks to maintain said spacing of said frames.

3. In a pair of goggles having lens frames and a exble, apertured, nose-bridge for connecting said frames; a hook mounted on one of said frames and having a horn extending adjacent the side of said frame with its end positioned to be engaged in apertures of said nose-bridge for connecting said frames in desired spaced relation; and a lens retaining cap on said frame enclosing said end of said horn for retaining said nosebridge engaged with said hook.

4. In goggles of the type described; lens frames each provided with a recess at one side thereof; lens retaining caps, a flexible nose-bridge for connecting said frames in spaced relation; a bridge retaining hook, said hook comprising; a base mounted inthe recess of one of said frames and a horn projecting from said base with at least the end thereof coniined between a portion of the lens cap associated with said frame and the base of said recess.

5. In goggles having a pair of lens frames and a exible nose-bridge for connecting said frames, said bridge having apertured portions; a bridge retaining hook, said hook comprising; a base secured to one of said frames and a rigid horn projecting from said base and extending adjacent the side of said frame with its end positioned to permit a selected aperture of said bridge to be slipped thereover for adjustably attaching said nose bridge to said frame; a lens retaining cap mounted on said frame; and means on said cap for conning at least the end of said horn between the inner side of said cap and said frame to maintain said nose-bridge engaged with said hook.

6. In goggles having a pair of lens frames, lens retaining caps mounted on said frames, and a nose-bridge chain for connecting said frames, a bridge retaining hook, said hook comprising; a base securedV to one of said frames; a exible horn projecting from said base with its end normally confined within the lens cap on said frame and engaging the associated lens; and reversely extending hook portions between said horn and said base forming a bight closed by the engagement of the end of said horn with said lens for retaining a chain link within said bight, said horn being adapted to be bent outwardly on removal of said lens cap to position its end outwardly of said frame for permitting the links of said chain to be slipped over said end and engaged with or disengaged from the bight of said hook.

7. In goggles of the type described, lens frames each provided with a recess at one side thereof; a flexible nose-bridge for connecting said frames; a bridge retaining hook, said hook comprising;

a horn extending within said'recessat the side of one of said frames and adapted to connect said nose-bridge to said frame; and a base to which said horn is connected, said base being mounted in the recess of said frame and having a slot for receiving a portion of said horn.

' 8, In goggles having a pair of lens frames and a nose bridge, having apertured portions, for connecting said frames; a bridge retaining member comprising, a base secured to one of said frames and a hook projecting from said base and having reversely. extending portions forming a bight and an end portion positioned to permit an :V

apertured-porti'on of said bridge to be slipped thereover for engagement with the bight of said hook to adjustably attach said bridge to said frame, said hook having between its juncture with said base and said bight a portion relatively larger than the aperture of said bridge for maintaining said .bridge portion outwardly of said base when engaged with said bight.

9. In goggles having lens Vframes and a nosebridge chain for connecting the latter; a bridge retaining hook secured to one of said frames and having an end-portion positioned to be engaged by a link of Vsaid chain for attaching said bridge to said frame; and a lateral projection on said hook end portion for facilitating sidewise engagement of a chainlink with said hook.

10. In goggles havingV a pair of lensv frames each provided with a recess at one side thereof; and an apertured nose-bridge for connecting said frames; a bridge retaining hook comprising a base mounted in the recess of one of said frames and a horn projecting from said base and having i a reversely extending end portion engageable by Vsaid nose-bridge for adjustably attachingpthe latter to said frame; and a lens retaining cap mounted on said frame and having a portion dis- Vposed between the base of said hook and the end
